Reseated all PC boards and connectors. Tested at various separation gaps from 1 to 800 microns. Align gap responding properly now. Possibly a bit was stuck and align gap setting not being interpreted correctly. Tested many times with mask and wafer  load/unload/expose. Reset the tool many times. Align gap working correctly now. Please report if problem returns
